my_function(line) Solution 2: TL;DR; All three of your suggested solutions are syntactically valid, and since you require a list for future manipulation, there is no superior or more pythonic option. The official Python documentation endorses all three, making them equally viable. Therefore, yo...

默认情况下,Readline 设置为由 rlcompleter 来补全交互模式解释器的 Python 标识符。 如果 readline 模块要配合自定义的补全函数来使用,则需要设置不同的单词分隔符。 readline.set_completer([function]) 设置或移除补全函数。 如果指定了 function,它将被用作新的补全函数;如果省略或为 None,任何已安装的补全函数将...

In the real world, you should prefer built-in functions to complex flow statements. Thezip()function would do a great job for this use case: >>> >>>list(zip(*matrix))[(1, 5, 9), (2, 6, 10), (3, 7, 11), (4, 8, 12)] #注意这里输出的全部变成了tuple元组了,跟上面的不同...
